[0003] At present, when installing steel columns and steel beams, one end of the steel beam is usually connected and fixed to the upper end of the steel column by welding, bolt connection or riveting. However, in some buildings, there is a certain angle between the steel beam and the steel column (the steel column is still vertical to the ground, and the steel beam is also parallel to the ground, but the two are not perpendicular to each other when connected). In this case, it is necessary to connect the steel column and the steel beam respectively through triangular connectors, so as to realize the "inclined" connection between the steel column and the steel beam. However, the above-mentioned triangular connectors are often at specific angles, which have certain limitations during the overall installation and cannot be reasonably adjusted according to the construction site, which is inconvenient.

[0023] like Figures 1 to 6 As shown, when installing the connecting device for building steel structure in the utility model, if it needs to be installed tilted to one side, it is only necessary to manually push the sliding assembly and the locking assembly toward one side of the support block 5 and the rotating block 7, so that the flip plate 6 can be rotated and unfolded to one side, thereby realizing the angle tilt between the steel column 1 and the steel beam 2. Moreover, due to the effect of the locking assembly, it can also be adjusted at any time according to the tilt angle required during installation, which is convenient, quick and more practical.
[0024] Please refer to Figure 2 and Figure 5The inner wall of the fixed plate 4 is provided with a plurality of slide grooves 401, and a plurality of sliding components are respectively located in the plurality of slide grooves 401.

[0025] More specifically, when the inclination angle of the steel beam 2 needs to be changed, the locking assembly only needs to be manually pushed along the slide groove 401, which can drive the slider 10 and the slide rod 11 to move together, and during the movement, the slider 10 can support the flip plate 6 to prevent it from being deformed easily.
